lvl 11 Paladin: Which units?

[eXeel]

I try to be a paladin mage, focus on that. I love ranged, but need a few melee too.
At the moment I have:

• 30 Evil Beholders, those from the Swamp. Great for dpsing and wasting an enemy stack's turn.
• 29 Mages. Those who can make shield, double damage and move a stack one cell. Great dps.
• 1200 peasants. Great dps, though slow. Easy to get. Cheap. Did I mention great dps?!
• 55 Inquisitors. Hard to get, can't by them anywhere, so I need 3 mind runes to get the talent, so I can turn priests into these. Then I'm set! Great dps and love the ress.
• 57 swordsman, or what the improved version is called. Not the footmen/swordsmen you get at first, but the ones after. I can't get them anywhere anymore, though! So in trouble with these.

I am happy about the first 4, the swordsman I would like to replace. But can't get enough Knights, and the Horsemen are too few too. And 4 ranged might be overkill. What do you suggest? Needs to be easy to get to and plenty of them! And then they need to do good dps or at least take a beating and have nice skills.

I'm on the Eastern and Western islands, trying to find my way into the mines and the hiding of that fellow, to continue the story.
Thanks
